UNSPSC 51241307: Allantoin

This classification denotes an astringent and anti-psoriatic agent with the molecular formula C4H6N4O3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 344S277G0Z, chemically known as 5-ureido-2,4-imidazolidindion but generally known as allantoin, which bears US NIH Compound Identifier 204. Allantoin comes in various forms, including acetyl methionine, ascorbate, biotin, glycyrrhetinic acid, n-acetyl-dl-methionine, and sodium succinate.

European Medicines Agency schedules Allantoin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12779MIG. Most nations schedule allantoin under HS 29332100 and SITC 51572. As of Q4 2014, ALLANTOIN remains the US FDA Preferred Term for this commodity. Allantoin bears US NLM identifiers UMLS ID C0002083 and NCI Concept Code C74277. SMILES: O=C1NC(=O)NC1NC(=O)N.

UNSPSC 51241307 Allantoin is a Commodity code that in recent state and local activity does not map to allantoin itself but rather to chemical treatment supplies for municipal water and wastewater operations. The City of Austin's IFB for liquid aluminum sulfate (alum) used in phosphorus removal at wastewater treatment facilities represents the code's actual procurement scope — municipalities are buying chemical coagulants and treatment agents to meet water quality standards. The second recent opportunity tagged to this code, a Tampa Fire Rescue ITB for medical aid supplies including antiseptic sprays, hydrogen peroxide, and bandages, falls outside the code's wastewater and water-treatment chemical scope and signals a tagging mismatch rather than a genuine commodity alignment. State and local buying under this code appears limited to municipal water and wastewater authorities procuring bulk chemical treatment products, not to allantoin or medical supplies.

The Austin solicitation (IFB 2200 CSH1061, due August 25, 2026) is the primary decision signal in the recent record. Austin Water is seeking 179,200 gallons annually of 47%–49% concentration unpackaged liquid aluminum sulfate, with vendors required to hold NSF approval, maintain 9,000-gallon minimum inventory at a distribution location within 500 miles, and provide three Texas municipal references. Local business preferences apply (5% discount up to $500,000), and pricing is firm for 12 months with adjustments capped at 25% annually. The opportunity shows typical water utility specifications: firm pricing, price-adjustment caps, distributed inventory requirements, and municipal reference documentation. No additional state or local opportunities under this code appear in the recent record. The narrow activity window and the Tampa medical-supplies tagging mismatch suggest this code sees sparse, inconsistent use in state and local procurement; pursuit should focus on direct relationships with municipal water and wastewater authorities in Texas and other states where alum or similar coagulant purchases are being managed through formal bid processes.
